Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the battery box is subjected to impacts and collisions, then the battery cells are prone to damage, but adding buffer members increases device complexity
Solution Approach 1:
The patent applies beforehand cushioning by arranging buffer members on the outer wall surface of the battery box before impacts occur. These buffer members have buffer surfaces that can intersect with both horizontal and vertical planes, providing pre-positioned protection against impacts and collisions from multiple directions, thereby reducing battery cell damage without requiring complex active protection systems.
Solution Approach 2:
The patent implements another dimension by configuring the buffer surface to intersect with both horizontal and vertical planes. This multi-directional buffer surface design provides buffering capability in multiple spatial dimensions simultaneously, enhancing protection against impacts from various angles while maintaining a relatively simple overall structure.
2Reliability
If the first buffer member is arranged on the outer wall surface with a buffer surface intersecting both horizontal and vertical planes, then buffering in multiple directions is provided, but the manufacturing complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the buffer surface into multiple buffer members arranged on different portions of the outer wall surface. Each buffer member can be manufactured independently with simpler geometries, and then assembled together to form the complete multi-directional buffer system, reducing individual manufacturing complexity while achieving comprehensive protection.
